SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 280,649Jdated July 3, 1883.

- Application filed March 24, 1883. (Model) To aZZ whom it may concern:

Be it known that I, JAMES MENzIEs, a citizen of Great Britain, residing at Fernandina, in the county of Nassau and State of Florida, have invented a new and Improved SealLock, of which the following'is a specification.

My invention relates to that class of locks which are adapted to be sealed by having their key-holes in some manner covered or made inaccessible, so that the key cannot be inserted without leaving evidence of the fact, and its object is to provide a simple device which may be attached to padlocks now in use on railway-cars or elsewhere, or they may be made as a portion of new looks, to so guard the keyhole that the key cannot be inserted after the guard is applied without leaving evidence of such act.

To this end it consists in the construction and combination of parts forming a seal-lock hereinafter described and claimed, reference being had to the accompanying drawings, in

which Figure 1 is a front elevation of a lock having my invention attached, and showingthe. same as locked and sealed; Fig. 2 is an edge view of the lock, showing the seal-holding device in vertical section.

A represents thebody of a padlock, the keyhole a being shown in dotted lines as covered by other parts.

B represents the frame of my attachment, secured to the face of the look by means of screws .or rivets, which may be concealed by any usual method or cast on the body of the lock at time of manufacture. This frame is open, like a window, in front of the key-hole a, and is provided with grooves in its two sides behind the front frame, 0, in which to insert a pane of glass, D, which I call the seal. The side grooves, c, are connected by a groove across the bottom to receive the lower edge of the seal. Directly under the seal, and plainly visible through it, is a card or paper, (1, on which is printed any desired headingsuch as L. and N. R. R. and any private marks un derstood by the sender and the receiversuch as the number 168 or as the name Louisville, Kentucky. This card or paper may be in any manner stuck to the back of the glass seal. Behind. the card or paper (Z is a hinged lid, 6, covering the key-hole, The seal is kept in place by an arm, E, secured to the pivot f of the keyhole to keep bits of the lock-shackle F, the lower extremity of arm E resting on the upper edge of the sealglass D. The shackle F is rigidly fixed to its pivot f to turn therewith, and when the lock is open the shackle F and its lower arm, E, are thrown over back, the arm E being out of the way, so that the seal may be readily inserted and the shackle may be hooked into the staple.

G is a guard, like the usual key-hole guard, pivoted catch to keep the guard in place.

The method of use is as follows: The sender marks the card or paper d as agreed upon between him and the receiver, shuts down the lid 6, tached, into grooves 0. Then, after closing the car-door and arranging its hasp, he hooks shackle F into the staple and shuts it into the lock, which, having a spring-bolt, holds it, and by means of arm E it also holds the seal D in its frame. vIn this condition there is no possible way of getting at the lock to unlock it without first breaking the seal. When the car reaches its destination and the receiver wishes to open it, he must first break the sealglass, then raise the lid which is placed over glass from entering the lock. Then he may apply the key and unlock it. Each road over which the car passes will be held responsible to see that the seal is unbroken and that the number or mark on the card accords with the way-bill, so that any robbery or peculation' can be located and charged to the defaulting road.

WVhat I claim as my invention; and wish to secure by Letters Patent, is-

slides the seal,with the marked card atto swing across the opening in frame B to protect the seal-glass, and g is a spring The combination, with a springp'adlock, A,

having its shackle pivot-pinj secured to the shackle F, to swing therewith, of an arm, E, secured to said pin, a grooved frame, B, secured to the face of the lock D, or other breakable cover for the key-hole, said arm E covering the entrance to said grooved frame when the shackle is locked down to prevent the removal of said seal, substantially as and for the purpose specified.
